🧵The Yarn

Stretch yarn designed specifically for creating crocheted swimwear and beachwear items. Made from 100% Tactel polyamide, this technical yarn provides superior elasticity, resistance to salt water and chlorine, and a soft-touch texture that makes it extremely comfortable against the skin.

Each 50-gram ball offers approximately 125 meters of yarn, perfect for making bikinis, one-piece swimsuits, sarongs, and cover-ups. It is worked with a 3.5-4 mm crochet hook or knitting needles of the same size, ensuring a compact and durable fabric ideal for use in the sea and pool.

🧬Technical composition: why it works

Tactel polyamide is a technical synthetic fiber developed specifically for sportswear and aquatic apparel. Unlike traditional cotton, polyamide does not absorb water, ensuring quick drying and shape retention even after numerous uses. Its molecular structure offers natural elasticity, allowing garments to adapt perfectly to the body without deforming.

Tactel fiber is also UV resistant, protecting the yarn's color from fading caused by prolonged sun exposure. This characteristic makes TOPLESS ideal for swimwear that maintains its brightness and vibrancy even after an entire summer season. Chlorine resistance ensures that garments made can be used in pools without fiber deterioration.

📦Yarn format and yield

Each ball of TOPLESS weighs 50 grams and offers approximately 125 meters of yarn. With one ball, you can make a size S bikini top or about half of a one-piece swimsuit. For a complete bikini (bra + briefs) in size S, 3 balls are recommended, while for larger sizes or one-piece swimsuits, 4-5 balls are needed.

For larger projects such as sarongs or cover-ups, estimate about 6-8 balls depending on the desired size. We recommend purchasing all necessary balls from the same dye lot to ensure perfect color uniformity in the finished garment.

🧶Recommended Work

TOPLESS is worked with a 3.5-4 mm crochet hook or knitting needles of the same size. A 3.5 mm crochet hook is ideal if you want a more compact and resistant fabric, perfect for swimwear that needs to maintain its shape in water. A 4 mm crochet hook offers a slightly softer and more breathable texture, ideal for cover-ups and sarongs.

To obtain a 10x10 cm swatch, you need 21 stitches x 26 rows with a 3.5-4 mm crochet hook. This gauge ensures an elastic yet compact fabric that provides the necessary coverage for functional swimwear. The yarn is also suitable for beginners thanks to its smooth texture that glides easily on the crochet hook

Unlike traditional elasticized cotton, TOPLESS is not attacked by moths, does not deform with repeated use in water, and maintains its original elasticity even after dozens of washes. Tactel polyamide offers superior mechanical resistance compared to natural fibers, ensuring garments that last over time without losing shape or color.

The soft-touch texture makes this yarn extremely comfortable against the skin, without the rough effect typical of some inexpensive synthetic yarns. After use in the sea or pool, garments made with TOPLESS dry quickly and do not require ironing, making them practical for those who travel or frequent the beach daily.

🎨What you can make

TOPLESS is the ideal yarn for crocheted bikinis, one-piece swimsuits, trikinis, and all beachwear items that require elasticity and water resistance. Thanks to its technical composition, it is also perfect for summer tops, sports tank tops, and beach accessories such as headbands and beach bags.

👩🎨Who it is suitable for

TOPLESS is suitable for both beginners and experienced crocheters. Its smooth and uniform texture glides easily on the hook, making the work fluid even for those approaching swimwear creation for the first time. The yarn does not fray and maintains constant tension during processing.

It is the ideal choice for hobbyists who want to create personalized swimsuits, artisans who sell handmade beachwear, and for those looking for a sustainable alternative to industrial swimsuits. Many customers also purchase it to make unique and personalized gifts for friends and family.
